ICT combines two nested transformers: a shorted one-turn current transformer loads the full bunch charge instantly into capacitors. Then the charge is transferred to the output by a readout transformer, at a slow pace, to avoid core losses. Cores are specially annealed to lower their coercive field and further minimize core loss. The ICT signal is integrated by BCM-IHR, a boxcar type synchronous differential detector. The output voltage proportional to the beam pulse charge is available 30μs after the trigger. It is maintained up to 400μs, then reset. Another pulse can then be measured.

In-flange ICT are mounted directly in the beam line.Available for many pipe diameters from 1” to 250mm.Also with elliptical aperture or other arbitrary shape aperture. Ceramic gap, shields and wall current bypass are included.Bellows are not required.Bakeable up to 185°C

UHV compatible

In-air ICT installation, over the vacuum chamber requires installation of a “gap” to prevent the wall current from flowing through the ICT aperture.

The gap can be a brazed ceramic ring or an organic material O-ring depending on the vacuum requirements.

Typical installations include bellows, a wall current bypass and an electromagnetic shield enclosing the ICT completely.

BCM-IHR-E processes the signal from an ICT.Specially developed hybrid circuits amplify the charge and integrate it with low noise and high linearity.Output is a bipolar voltage directly proportional to the beam charge.A built-in Calibration Generator provides on-line assurance of measurement reliability.BCM-IHR-E inserts into a wired station of BCM-RFC, the 19” 3U RF-shielded chassis including power supplies.Up to 10 stations per chassis can be installed.
